実験手順

A mixture of 6 g of ethyl 4-(imidazo[1,2-a]pyrimidin-2-yl)phenyl-acetate, 30 ml of ethanol, 1.1 g of sodium hydroxide and 5 ml of water is stirred at room temperature for 10 minutes. The crystalline precipitate is filtered off, washed with ethanol, and then dissolved in water. The solution is adjusted to pH 6 by addition of dilute hydrochloric acid. The crystalline precipitate is filtered off and washed with water to give 3.2 g of 4-(imidazo-[1,2-a]pyrimidin-2-yl)phenylacetic acid as colorless crystals melting at 264°-265°C with decomposition.
